Definitions

  • the invention relates to an optical device adapted to be worn by a wearer comprising a programmable lens and an optical function controller.
  • an active lens permits a variation of the optical power or prism of the lens while being worn by a wearer. For instance, it exists active lenses with a manual adjustment of the optical power or prism of the lens.
  • an active lens When focused on the wearer's needs, an active lens induces a variable prismatic deviation and a strong and disturbing apparent motion appears.
  • active lenses such as Fresnel lenses with additional power limited to field of view of the wearer, which are automatically activated when the wearer lows his head.
  • active lenses comprising an optical component stacked between two perpendicular active Fresnel cylindrical lenses.
  • the resulting spherical power is centered according a fixation point.
  • the optical function seen by the wearer is equivalent to a mobile patch skating or jumping on the lens according to his gaze direction or to his head orientation which moreover may occur at the wrong time.
  • embedded gaze-tracking devices have high power consumption, latency, errors and dysfunction.
  • Such limitation are, for instance, noticeable while a wearer sits and uses his phone, or his tablet, or his computer, or when a wearer is at the top of a stair and lows his head to adjust his foot placement to go down.
  • the steps of the stair can suddenly move, according to the head motion, the eye-tracker calibration, or the lighting, and the wearer can fall down. Indeed, it may cause a misaligned and blurred vision while descending the stairs.
  • a control loop of the optical function based on gaze direction need to be very finely adjusted to avoid unbearable oscillations or drifts.
  • One object of the invention is to provide such an optical device.
  • an optical device adapted to be worn by a wearer comprising at least:
  • the optical device according to the invention allows a variation of the optical function while the optical device is worn by the wearer.
  • the optical function of the programmable lens may be adjusted over a period of time during which the wearer does not perceive the adjustment of the optical function.

  • the invention relates to an optical device adapted to be worn by a wearer.
  • the optical device 10 may be a head mounted device, as represented in figure 1 , comprising a frame 12.
  • the optical device 10 comprises at least one, for instance two, programmable lens 20.
  • the programmable lens 20 may be an active programmable lens.
  • the programmable lens 20 have an adjustable optical function.
  • the programmable lens 20 is configured to extend between at least one eye of the wearer and the real world scene when the optical device is worn by the wearer.
  • the optical device 10 comprises an optical function controller 30.
  • the optical function controller 30 comprises a memory 32 and a processor 34.
  • the memory 32 is configured to store computer executable instructions.
  • the memory 32 may also be configured to store data received by the optical function controller 30.
  • the processor 34 is configured to execute the stored computer executable instructions so as to control the optical function of the programmable lens 20.
  • the computer executable instructions comprise instructions for adjusting the optical function of the programmable lens 20 over a period of time determined so that the wearer does not perceive the adjustment of the optical function.
  • the computer executable instructions may comprise instructions for adjusting the optical function of the programmable lens 20 over a period of time determined so that the adjustment of the optical function corresponds to wearer's preferences or to wearer's needs, and more precisely to the wearer's visual preferences or to the visual wearer's needs.
  • the predetermined period of time is smaller than 50 ms.
  • the predetermined period of time is smaller than 20 ms so that the wearer does not perceive the adjustment of the optical function.
  • the adjustment of the optical function may be applied on a part of the field of view of the wearer or in the whole field of view of the wearer.
  • the adjustment of the optical function may be applied on a part of the programmable lens, or on the whole programmable lens.
  • the optical function may remain constant in the central vision of the wearer and may be adjusted in the peripheral vision of the wearer.
  • the optical function may comprise the dioptric function, the light absorption, the polarizing capability or the reinforcement of contrast capacity.
  • the dioptric function corresponds to the programmable lens power, for instance the mean power or the astigmatism, as a function of the gaze direction.
  • the optical function of the optical device may comprise a sun protection function, for example by controlling a transmission parameter of the programmable lens or the polarization of a surface of the programmable lens.
  • the programmable lens 20 may be an optical lens, an ophthalmic lens, a spectacle lens, a progressive or single vision lens.
  • the programmable lens 20 may comprise a succession of single vision, for instance unifocal, designs on the lens, or a succession of progressive power lenses.
  • a succession of progressive power lenses instead of a succession of single vision designs, the number of transition states for the adjustment of the programmable lens is reduced, and thus, the risk of potential discomfort of the wearer is limited.
  • a wearer suffering from presbyopia may practice three different activities at different gazing distance.
  • the wearer may need a far vision correction, for example for watching TV or driving, an intermediate vision correction, for example for looking at his computer, and a near vision correction, for example for looking at his phone or reading a book.
  • a succession of single vision corrections on the programmable lens is used, when the wearer needs to use the far vision correction, then the intermediate vision correction, and then the near vision correction, three different corrections adapted to the three different distances need to be proposed.
  • two transitions states for the adjustment are managed.
  • the wearer may have a first vision correction adapted to the far and intermediate vision activities and a second vision correction for the intermediate and near vision activities. If the wearer needs to use the far vision correction, then the intermediate vision correction, and then the near vision correction, only one transition is managed, and thus the number of transition states is reduced relative to the use of a succession of single vision corrections on the programmable lens.
  • the progressive lens may comprise a progressive power lens or a succession of progressive power lenses.
  • using a succession of progressive power lenses instead of a progressive power lens, reduces the optical constraints. For instance, by adapting the progressive power lens to activities that need a specific vision distance, the amount of power added by the programmable lens is reduced. Indeed, for a distance vision from 33 cm to the infinite, a greater value of power is needed on a progressive power lens than on a succession of progressive power lenses, for instance comprising two progressive power lenses, one being adapted for a distance vision from 33 cm to 63 cm, the other being adapted for a distance vision from 63 cm to the infinite.
  • the fields of view of a succession of progressive power lenses are larger, more stable and adapted to the activity of the wearer over the time, than the field of view of a progressive power lens where the intermediate vision can be less stable and narrower than the far vision.
  • the quantity of aberrations in the periphery is reduced relative to in a progressive power lens.
  • the progression length of a succession of progressive power lenses may be adapted to the activities and reduced to be closer to a "natural" near vision posture than on a progressive power lens where the near vision may be located too low in the lens due to conception or fabrication constraints.
  • the use of a succession of progressive power lenses may free the direction or axis of the variation of the power on the programmable lens.
  • the direction of the variation of the power may vary in the programmable lens, depending on the activity of the wearer. For example, instead of having a variation from the upper part to the lower part of the lens, the situation may be switched to have a near vision correction in the upper part of the lens, for postures that are different than classical ones, for example for fixing something on a wall, or watching TV lying on a sofa, or reading a book lying in a bed. Plus, a variation in a different direction, like into the left or into the right, for other specific activities may also be managed.
  • the optical device 10 may comprise an eye sensor 40.
  • an eye sensor 40 is an eyeball sensor, for instance an eyeball rotation sensor or an eyeball position sensor, or an eyelid sensor.
  • the eye sensor 40 is adapted to measure eye data relating to the eye movement of the wearer using the optical device 10.
  • the computer executable instructions may comprise instructions for adjusting the optical function of the programmable lens 20 when the eye data indicate that the eye of the wearer is closed.
  • the computer executable instructions may comprise instructions for adjusting the optical function of the programmable lens 20 when an eye-blink of the wearer is detected.
  • An eye-blink is a fast closing of an eyelid useful to, at least, spreads tears and cleans the surface of the cornea and conjunctiva.
  • An eye-blink is also useful to protect the eye from damages, and cuts the wearer's attention, during tiredness or sleep.
  • the computer executable instructions may comprise instructions for adjusting the optical function of the programmable lens 20 at a rate below the perception rate of the wearer.
  • the adjustment of the optical function of the programmable lens may be done slowly, namely with a small step, such that the wearer does not perceive that the optical function is different between two consecutive values of optical function separated with the step.
  • a prismatic deviation in at least one position of the programmable lens may be slowly introduced such that the adjustment of the optical function can be invisible for the wearer. More precisely, with a prismatic displacement gradually introduced on the programmable lens, the wearer may not be aware of the prismatic displacement on the programmable lens.
  • the perception rate of the wearer depends on the mobility of the wearer, namely depends on if the wearer is moving or not.
  • the optical function need to be adjusted slower than when the wearer is motionless in order to avoid an imbalance of the wearer.
  • the prismatic variation speed may be smaller than 1.75 prism diopters per second, and more precisely smaller than 0.85 prism diopters per second, when the wearer is in motion. Such prismatic variation speed corresponds to a situation where a wearer fixates a point on a side at 10 meters while walking.
  • the adjustment of the optical function of the programmable lens may be done quickly, namely with a high speed, such that the wearer does not perceive the moment when the optical function is adjusted.
  • the adjustment of the optical function of the programmable lens may be done during an ocular saccade or an eye-blink.
  • the perception rate of the wearer is around 50 ms, and the optical function may be adjusted with a speed of adjustment smaller than 50°ms such that the wearer does not perceive the adjustment of the optical function.
  • the optical device 10 may comprise a vision sensor 50.
  • the vision sensor 50 is adapted to measure vision data relating to the vision direction and/or vision distance of the eye of the wearer using the optical device 10.
  • the vision sensor 50 may be a camera or an eye-tracking device.
  • the speed of the ocular saccade, namely the rotation speed of the eyeball, may be taking onto account to indicate the size of the ocular saccade or the distance of the next fixation area.
  • the computer executable instructions may comprise instructions for adjusting the optical function of the programmable lens 20 when the vision data indicate an ocular saccade of the eye of the wearer.
  • An ocular saccade is a type of ocular motion, defined by a fast eye rotation from 100 degrees per second to more than 600 degrees per second.
  • an ocular saccade permits to move quickly the fovea, the high resolution area of the retina, towards a special point of interest to observe during fixations or pursuits, where the gaze direction is maintained aligned on an environment or a moving object.
  • this very fast motion in normal condition, without strobe or flash, an image cannot be perceived by the wearer due to its fast sliding on the retina.
  • eye-blinks and ocular saccades are concomitant.
  • the eye position is naturally disrupted by error in carrying out the ocular saccade or a motion induced by the eyelid friction.
  • a not perceived post reflex re-adjusts the gaze direction.
  • the optical function, and for instance the prism may be adjusted during an eye-blink or an ocular saccade so that the adjustment is not perceived by the wearer.
  • the wearer is looking through a first area of the programmable lens, and while exploring the environment, the wearer have an ocular saccade during which his gaze direction is moved toward a second area of the lens, for example distant from the first area.
  • An eye-tracker is not able to measure this phenomenon, since it is comprised between 20 ms and 200 ms, which is too fast to be measured.
  • the wearer's gaze direction stays long enough in the second area, for instance 0.5 second or more, the gaze direction of the wearer may be measured and the programmable lens may adjust the prism in at least one position of the programmable lens during the next eye-blink or the ocular saccade.
  • the wearer's gaze direction may stay long enough in the second area, and it might be anticipated by the computer executable instructions if the programmable lens needs it.
  • Such adjustment may be near from the previous value of the prism, for instance a difference between the two consecutive values of prism smaller than 5 degrees, which is the amplitude of a normal corrective ocular saccade.
  • Such adjustment may be repeated and modulated according to specific criteria, such as the wearer's activity, for instance reading, watching a screen, doing manual activities, or moving.
  • the wearer's activity may be measured in real time by using an inertial measurement unit (IMU).
  • IMU comprises an accelerometer for detecting the frequency and the amplitude of the movement of the head of the wearer and a gyroscope.
  • the optical function of the programmable lens may be adjusted depending on the activity of the wearer detected by the IMU or indicated by the wearer, for instance in a list of pre-programmed activities. For instance, if a wearer do archery, even if the wearer moves, for example for catching an arrow, the optical function of the programmable lens may be maintained with the far vision correction. If a wearer paint a landscape, even if the wearer moves his head, the optical function of the programmable lens may be maintained with the far and intermediate or near vision correction.
  • the adjustment may be applied to the programmable lens before the end, or close to the end of the ocular saccade or eye-blink.
  • the optical function when using an optical device having a low speed programmable lens, the optical function may be adjusted at the beginning of the detection of an ocular saccade or eye-blink, in order to ensure that the adjustment of the optical function is finished before the end of the ocular saccade or eye-blink.
  • the optical function may be adjusted with a high speed programmable lens during an ocular saccade or eye-blink, or at a time close to the end of the ocular saccade or eye-blink, for instance at a time smaller than 20 ms.
  • the adjustment of the optical function appears during an ocular saccade or eye-blink, the adjustment is not perceived by the wearer.
  • the adjustment of the optical function may be accurate or may be an estimate, and after the ocular saccade or eye-blink, a high accuracy eye-tracking device can be conducted, for instance using the average of measurements of high speed and low accuracy eye-tracker, and a low adjustment of the optical function may be used to reach the desired optical function.
  • the optical function may be adjusted only during an ocular saccade or blink, and may not be adjusted, or may be slowly adjusted at other moments.
  • the computer executable instructions may comprise instructions for adjusting the optical function of the programmable lens 20 when the vision data indicate a vertical and/or horizontal ocular saccade of the eye of the wearer.
  • the vision sensor 50 may be adapted to measure consecutive ocular saccades, for instance two consecutive ocular saccades.
  • the vision sensor 50 may be adapted to measure the speed of the ocular saccade so as to anticipate the next gaze position.
  • the ocular saccade speed and the ocular saccade size may be determined from the behavior of the wearer.
  • the computer executable instructions may comprise instructions for adjusting the optical function of the programmable lens 20 when the vision data indicate a second ocular saccade of the eye of the wearer.
  • the computer executable instructions may comprise instructions for adjusting the dioptric function or the optical power of the programmable lens 20.
  • the optical power of the programmable lens may be adjusted by moving the optical power of the programmable lens with the vision distance of the wearer.
  • the optical device 10 may comprise a position sensor 60.
  • the position sensor 60 is adapted to measure position data relating to the position of a reference point of the programmable lens 20 of the optical device 10 relative to a reference point of an eye of the wearer.
  • the reference point of the eye of the wearer may be the center of rotation of the eye of the wearer.
  • the position sensor 60 may be a capacitive sensor.
  • the computer executable instructions may comprise instructions for adjusting the optical power of the programmable lens 20 based on the position data.
  • the position of the optical device relative to the wearers' head may be measured to adjust the optical power.
  • the frame of the optical device may slide on the nose of the wearer from a first, initial, position to a second, new, position, and the new position of the optical device may be taken into account for adjusting the optical function of the programmable lens.
  • the adjustment of the optical power of the programmable lens 20 may be smaller than or equal to 0.25D, and preferably smaller than or equal to 0.12D.
  • the computer executable instructions may comprise instructions for adjusting the prism at least in one position of the programmable lens 20.
  • the prism in at least one position of the programmable lens may be changed when modifying the spherical or cylindrical power or axis of the programmable lens at least in one position, and/or when modifying the optical center of the programmable lens, namely the position for which the prism is equal to zero.
  • the computer executable instructions may comprise instructions for adjusting the transmission function of the programmable lens 20.
  • the optical device 10 may comprise two programmable lenses 20, each programmable lens having an adjustable optical function.
  • a programmable lens 20 extends between the right eye of the wearer and the real world scene when the optical device is worn by the wearer.
  • the other programmable lens 20 extends between the left eye of the wearer and the real world scene when the optical device is worn by the wearer.
  • the computer executable instructions may comprise instructions for adjusting the optical function of both programmable lenses 20.
  • the computer executable instructions may comprise instructions for adjusting the optical functions of both programmable lenses 20 independently one from the other. For instance, if the wearer have different corrections for the right and left eyes, it may be advantageous to adjust the optical function of only one of the programmable lens, or to adjust the optical function of the programmable lenses independently one from the other. Moreover, only one of the optical function of the programmable lenses may need to be adjusted. Plus, the right and left eyes of the wearer may have different sensitivities, and thus a different adjustment of the optical function may be needed for the right and left eyes.
  • the programmable lenses may be adjusted at the same time or at different moments, according to the wearer's preferences or to the wearer's needs.
